Specification of Letters Patent.

Patented Dec. 25, 1906.

Application filed May 24,1906. Serial No. 318,569.

To a/ZZ whom, it mfc/y concern:

Be it known that I, LAMBERT ZEIGLER, Sr., a citizen of the UnitedStates, residing at Lyons, in the county of Clinton and State of Iowa,have invented a new and useful Woodworking-Machine, of which thefollowing is a specification.

This invention relates to tables for woodworking-machines, and has forits object to provide a sectional table, the parts of which can beadjusted to different elevations in relation to each other and to thesupportingframe of the table, whereby the panels or other stock to beoperated upon can be held rmly in place even though their surfaces be ofirregular contour.

In woodworking-machines utilizing scoring-knives and cutter-heads it isdesirable not only to have a table which will hold the stock firmly inplace even though it be warped, but it is also necessary to have simplemeans whereby the stock can be quickly adjusted toward or away from thecutting mechanism of the machine. l

One of the objects of the invention is to provide simple and eicientmeans for obtaining this result.

' l/Vith the above and other objects in view the invention consists ofcertain novel features of construction and combinations of parts whichwill be hereinafter more fully described, and pointed out in the claims.

In the accompanying drawings is shown the preferred form of theinvention.

In said drawings, Figure 1 is a front elevation of a table constructedin accordance with the present invention, a cutter-head heilig shown inposition beneath the table. Fig. 2 is a view, partly in plan and partlyin horizontal section, of the table-sections and of the adjoiningportion of the supportingframe, only a part of the outer table-sectionbeing shown. Fig. 3 is a section on line a a, Fig. 1. Fig. 4 is asection on line b b, Fig. 1, showing only a portion of the outertablesection and of the supporting-frame. Fig. 5 is a section on line cc, Fig. 1. Fig. 6 is a plan view of one of the slides of thesupporting-strips, and Fig. 7 is a detail view of a supporting-strip.

Referring to the figures by characters of reference, 1 is asupporting-frame of any suitable construction, on which is disposed abed 2, having an enlarged central opening 3.

Mounted upon cross-strips 4, connecting the sides of thesupporting-frame near the bottom thereof, are standards 5, in 'which isjournaled a shaft 6, having beveled gears 7 at the ends thereof andmeshing with similar gears S, secured upon vertical shafts 9 and 10,respectively. These shafts are j ournaled at their lower ends in thecross-strips 4, and the shaft 9 is provided at its upper end with acrank 11, 'whereby the shaft may be rotated manually. Each shaft 9 andl0 has a screw-threaded portion 12, and these threaded portions extendthrough and engage ears 13, which extend inwardly through the side ofthe supporting-frame and from a baseslide 14, which is mounted upon saidside of the frame. It is therefore obvious that whenever the shaft 9 isrotated, as by means of the crank 11, the threaded portion 12 thereofwill move the ear 13 longitudinally thereof, and at the same time rotarymotion will be transmitted through shaft 6 to shaft 10, so that the ear13 will be moved longitudinally of said shaft 10. Both ends of thebase-slide can therefore be adjusted upward and downward simultaneouslyby an operator standing adjacent the crank 11. A slot 15 is formedwithin the central portion of the base-slide. Arranged upon the innerface of the base-slide 14 are guide-cleats 16, between which is mountedAa slidable bracket 17, having guides 18 disposed on the top thereof andengaging a slide 19, on which is mounted a rotatable shaft 20, carryinga pulley 21. An ear 22 extends upward from the free end of the bracket,and mounted within it is an adjusting-screw 23, which is swiveled in theslide 19, and by manipulating this screw said slide can be movedlongitudinally upon the bracket. A cutter-head 24 is secured to thatportion of the shaft 20 which 95 projects through the side of the frame,and it is obvious that when the pulley 21 is rotated, by means of a belt25 driven by any suitable power, this head will be rapidly revolved. Byturning the screw 22 in either direction the entire shaft can beadjusted longitudinally, so as to move the cutter-head toward or awayfrom the base-slide. A guide-bolt 26 extends from the brackets 17 andthrough the slot l5, said bolt being provided with a head 27, whichoverlaps the walls of the slot. This bolt constitutes a guide for thebracket and at the same time holds it tiO'htly against the base-slide.ln order that tzhe base-slide may be retained in proper relation withthe IOO side of the supporting-frame 2, guide-cleats 28,/are securedthereto or formed therewith and overlap the walls 29 of the large frontopening 30 within the side of the supportingframe 2. It will thereforebe seen that the base-slide and the bracket 17 connected thereto can bereadily adjusted by means of the shaft 9 and the parts operated thereby,and an independent vertical adjustment of said bracket 17 is attained bymeans of an adjusting-screw 31, which bears upon the bottom of thebracket 17 and is screwed through an ear 32, extending inwardly from thebase-slide, as shown particularly in Figs. 1 and 3.

Extending from the ends of the base-slide 14 are brackets 33, supportingthe intermediate table-sections 34 and provided at their front ends withalining ilanges 35. A space 36 is Jformed between the table-section 34and the base-slide 14, and projecting beyond the flanges 35, with itsupper face flush with the top of the table-section 34, is a tongue 37,having its lower face formed with an angular recess 38. One of theflanges 35 has a portion of its lower edge inclined, as shown at 39, andprovided with an ear 40, in which is mounted an adjusting-screw 41. Thisadjusting-screw bears against an ear 42, which extends from thebase-section 43 of the outer table-section 44. Two of thesebase-sections are employed, one near each end of the table, and brackets45 connect the base-sections with the table-sections. Angular tongues 46are formed upon the base-sections 43 and partly overlap the inner edgeof the tablesection 44, and these tongues are adapted to be seatedwithin the groove 38, so as to bind the table-sections 34 and 44 tightlytogether. Parallel inclined slots 47 are formed in the two base-sections43, and projecting through. these slots are guide-bolts 48, which extendfrom the flanges 35. It will be understood from the foregoing that byrotating the screw 41 within ear 40 the base-sections 43 of the outertable-section 44 can be raised or lowered in the direction of thediagonal slots 47 so as to lift the table-section 44 into position(shown in Figs. 3 and 4) or to lower said table-sections to a desiredpoint in relation to the intermediate section 34 Guide-cleats 49 arearranged in pairs upon the outer face of the base-slide, and mountedbetween each pair of these cleats is a slide 50, having anoutwardly-extending ear 51, bearing upon an adjusting-screw 52. Theseadjusting-screws extend through ears 53 upon the base-slide, and byturning said screws the slides can be` moved upward or downward. Eachslide 50 has an outwardly-extending flange'54, provided withlongitudinally-extending slots 55, and slidably mounted on the twoslides 50 and their flanges 54 are supporting-strips 56, which extendbetween the table-section 44 and the base-slide and haveoutwardly-extending flanges 57, from which extend guidebolts 58, whichare slidably mounted in the slots 55. These supporting-strips have theiradjoining ends undercut or beveled, as shown at 59, so that if thecutter-head is not in use the two supporting-strips can be slid towardeach other, so as to bridge over said cutter-head. It is of courseunderstood that an opening 60 is formed within the intermediatetable-section 44 to permit the cutterhead to be adjusted upward ordownward therethrough.
